The lintels used for seating are salvaged from the infirmary that the park replaced. The pavers absorb the park’s rainwater runoff from the grassy areas. Perhaps most interestingly is how the paving system can absorb pollutants from the air and fix them through a process using photocatalytic cement. The cement acts as a catalyst for oxidization of the pollutants. The pavers even stay cleaner than other products, thus reducing maintenance costs.
